Abstract

The present invention is related to a method for establishing a communication session between a client and a server. The method comprises the steps of

• • receiving at said server a request for network resources for establishing the client-server communication session, said request at least comprising an identification of the client,
  • collecting at the server information on available network resources for the client-server communication session, and
  • establishing the communication session with the client taking into account the information on available network resources.

Claims

1. Method for establishing a communication session between a client and a server, said method comprising the steps of

receiving at said server a request for network resources for establishing said client-server communication session, said request at least comprising an identification of said client,

collecting at said server information on available network resources for said client-server communication session, and

establishing said communication session with said client taking into account said information on available network resources.

2. Method for establishing a communication session as in claim 1, wherein at least a part of said information on available resources is comprised in said request for network resources.

3. Method for establishing a communication session as in claim 2, wherein at least a part of said information is added to said request by said client.

4. Method for establishing a communication session as in claim 2, wherein at least a part of said information is added to said request along the transmission path between said client and said server.

5. Method for establishing a communication session as in claim 1, wherein at least a part of said information is provided by said server.

6. Method for establishing a communication session as in claim 1, wherein at least a part of said information is provided by an external device capable of performing communication management.

7. Method for establishing a communication session as in claim 1, wherein said communication session is a video-on-demand or a linear programming TV service.

8. Method for establishing a communication session as in claim 1, wherein said communication session is established via a unicast stream from said server to said client.

9. Method for establishing a communication session as in claim 1, wherein said communication session is at least partially performed in a burst mode.

10. Method as in claim 8 for implementing a fast channel change requested by a client in a linear programming TV service, wherein the server sends an anchor frame to said client in unicast for allowing fast picture building.

11. Device arranged for acting as a server in a client-server communication session, said device comprising means for receiving a request from a client for network resources, wherein said device is further arranged for receiving information on available network resources for said client-server communication session and for establishing said communication session taking into account said information on available network resources.

12. Device for use in a communication session between a client and a server, wherein said device is arranged for adding information on available network resources to a request to said server for network resources.

13. Device as in claim 12, further arranged for generating said request for network resources.

14. Device as in claim 12, being a modem or an access multiplexer.
